      Finite Groups in Stone-Čech Compactification

      Shaymaa, M. Mostafa (the islamic university, 2010)
      Let κ be an infinite cardinal. Let G = ۔Åα<κGα where Gα is a nontrivial group. Now let βG be the Stone-Cech compactification of G and let H = ∩α<κ{clβG{x ∈ G \ {e}: min supp(x) ≥ α}: Then we will show that H contains no ...
